Air Source Heat Pump Water Heaters Powered by CO2

Aegis is a highly efficient, commercial heat pump solution that uses electricity and natural refrigerant-grade CO2 to produce domestic hot water up to 185°F all year round.

Aegis comes in two versions: Aegis A and Aegis W. Aegis A absorbs and moves heat from the surrounding air at temperatures as low as -4°F to produce hot water. Aegis W produces hot water by absorbing and moving heat from a connected water source at temperatures as low as 14°F.

Adapt to No-Gas Laws and Electrification Initiatives

Future-proof your water heating system from stricter environmental laws

An increasing number of cities and states are implementing laws that ban the use of natural gas in new buildings – or in other ways limit or disincentivize its use. In certain cases, laws even specify the use of heat pumps.

Using electricity and the superior qualities of R744*, a natural refrigerant-grade CO2, Aegis heat pump water heaters are among the cleanest, most efficient and environmentally friendly ways to heat domestic water.

  • Coefficient of Performance of 5.0 or higher
  • Non-toxic and non-flammable refrigerant
  • No negative impact on the ozone layer
  • Global Warming Potential (GWP) of just 1.0

*R744 outperforms other refrigerants, like R134a and R410a, by having a much lower GWP (1.0 vs 1430 and 2088 respectively) and a wider range of ambient operating temperatures, making Lync’s Aegis heat pump a better, longer-lasting option as more states introduce stricter environmental guidelines.

High Performance and Energy Saving Operation

Aegis comes as a single-source system solution, which provides buildings with an industrial heat pump water heating system optimized for maximum output and efficiency. Duplex stainless-steel tanks allow for higher water temperatures and outdoor usage.

The wide ambient operating conditions of Aegis provide a high COP throughout the year, which translates into lower energy bills. Whereas a gas-fired or electric resistance water heater is physically limited to a theoretical COP of 1.0, i.e. 100%, the Aegis heat pumps can achieve a COP of 5.0 or higher. By absorbing the “free” heat in the surrounding air or water rather than heat being generated by electricity or from a fuel source, less energy is needed to produce the same heat output.


The Aegis line of air source heat pump water heaters feature hot water production up to 194°F/90°C and an ambient operation from -4°F/-20°C to 113°F/45°C. They are ideal for both new and retrofit applications and can be used in a variety of commercial facilities including:

  • Hotels & Hospitality
  • Office Buildings
  • Universities & Dorms
  • Residential High Rises
  • Industrial Facilities
  • Healthcare Facilities
  • Restaurants
  • Multifamily
  • Gyms
